- FIG. 1 shows a cross-sectional diagram of an embodiment of a tool 100 A for use in a degradation assembly inserted within a bore 121 A of a driving mechanism 125 A with magnified portion.
- the degradation assembly 100 A has an impact tip 102 A attached to a carbide bolster 101 A.
- the impact tip 102 A may comprise a superhard material 104 A attached to a cemented metal carbide substrate 103 A.
- the super hard material 104 A may be diamond, polycrystalline diamond with a binder concentration of 1 to 40 weight percent, cubic boron nitride, refractory metal bonded diamond, silicon bonded diamond, layered diamond, infiltrated diamond, thermally stable diamond, natural diamond, vapor deposited diamond, physically deposited diamond, diamond impregnated matrix, diamond impregnated carbide, monolithic diamond, polished diamond, course diamond, fine diamond, nonmetal catalyzed diamond, cemented metal carbide, chromium, titanium, aluminum, tungsten, or combinations thereof.
- the super hard material 104 A may be a polycrystalline structure with an average grain size of 10 to 100 microns.
- the carbide bolster 101 A has a cavity 105 A into which a first end 177 A of a stem 113 A is inserted.
- the cavity 105 A includes a lip 150 A defined by a portion of the cavity 105 A having a lip diameter 175 A smaller than a cavity diameter 176 A.
- the first end 177 A of the stem 113 A includes an enlarged portion having a stem diameter 180 A less than the lip diameter 175 A.
- the stem 113 A may be held in place using a snap ring 106 A having an snap ring outer diameter 178 A greater than the lip diameter 175 A and a snap ring inside diameter 179 A less than the stem diameter 180 A.
- the snap ring 106 A is inserted into the cavity 105 A and disposed between the stem 113 A and a lip 150 A of the bolster 101 A.
- a tightening assembly 140 A within the tool 100 A is adapted to apply tension between the bolster 101 A and an anchor 111 A through the stem 113 A.
- Tightening assembly 100 A may include springs 110 A disposed around the stem 113 A and adapted to push off the anchor 111 A to apply tension to the stem 113 A.
- An insert 109 A is disposed around the stem 113 A and between the bolster 101 A and springs 110 A.
- a threadform 112 A may connect a nut 160 A to the stem 113 A to provide a surface for the spring 110 A to load the stem 113 A.
- An anchor 111 A may have barbs 120 A that engage a wall 122 A of the bore 121 A of the driving mechanism 125 A to secure an insert 109 A within the bore 121 A upon insertion of the tool 100 A into the bore 121 A.
- a steel ring 107 A is disposed between the bolster 101 A and a meltable spacer 108 A.
- the meltable spacer 108 A is adapted to melt when heat is applied to the tool 100 A through the carbide bolster 101 A. As the meltable spacer 108 A melts, the tension on the stem 113 A pulls the bolster 101 A closer to the anchor 111 A, effectively tightening the connection. The tightening assembly 140 A pulls on the carbide bolster 101 A thus securing the bolster 101 A to the driving mechanism 125 A.
- the meltable spacer may comprise lead, bismuth, tin, cadmium, wax, plastic or combinations thereof.
- the meltable spacer 108 A may melt at a temperature significantly lower than the bolster 101 A and/or stem 113 A.
- the meltable spacer may be a ring, a shim, wedge, ball, cube, roller, arc segment, or combinations thereof.
- the meltable spacer 108 A has a characteristic such that when it changes from a solid phase to a liquid phase, the phase change occurs rapidly.
- the pull down stroke is no greater than an inch.
- the lip the lip may be formed by molding, grinding, or a CNC process.
- the springs 110 A may be Bellville springs, biased rings, coil springs, gas springs, rubber, an elastomeric material or combinations thereof.
- the springs 110 A may also provide the benefit of providing a variable pull down force on the bolster 101 A.
- tools, such as tool 100 A will heat up while in operation causing all of the components to thermally expand.
- the bolster 101 A will have a lower coefficient of thermal expansion that the material forming the bore wall 122 A and therefore the bore wall 122 A may want to separate from the bolster.
- the pull-down force of the springs 110 A will keep the bolster 101 A snug against the bore wall 122 A under the differing temperature and expansion changes.
- the invention is especially well suited for applications where inserts or some kind of connection is in needed to be made in a blind hole.
- FIG. 2 a shows a cross-sectional diagram of another embodiment of a tool 100 B inserted within the bore 121 A of the driving mechanism 125 A.
- a wall 122 A of the bore 121 A has a series of stepped notches 210 B adapted to fit to an increased size of an insert 109 B.
- the used tool 100 A is removed from the bore 121 A and replaced with another assembly 100 B.
- the newly inserted assembly 100 B includes at least one barb 120 B on an anchor 111 B such that upon insertion of the tool 100 B, the at least one barb 120 B contacts the wall 122 A of the bore 121 A at a location different than where the previous barb 120 A engaged the wall 122 A of the bore 121 A.
- FIG. 2 b shows another cross-sectional diagram of another embodiment of a tool 100 C inserted within the bore 121 A of the driving mechanism 125 A.
- the wall 121 A of the bore 122 A includes the series of stepped notches 210 B adapted to fit to the increased size of the insert 109 C.
- the used tool 100 B is removed from the bore 121 A and replaced with another tool 100 C.
- the newly inserted tool 100 C has at least one barb 120 C disposed such that upon insertion of the tool 100 C, the at least one barb 120 C contacts the wall 122 A of the bore 121 A farther from a bottom 150 B of the bore 121 A than a point of contact of the previous tool 100 B.
- FIG. 3 shows another cross-sectional diagram of another embodiment of a tool 100 D inserted within a bore 121 D of a driving mechanism 125 D.
- a stem 113 D is restricted from removal from a cavity 105 D of a bolster 101 D by a snap ring 106 D disposed around the stem 113 D and a notch 300 D disposed on an enlarged portion 305 D of the stem 113 A.
- the snap ring 106 A contacts a wall 301 D of the cavity 105 D and the notch 300 D, thus restricting the removal of stem 113 D from the cavity 105 D.
- FIG. 4 shows another cross-sectional diagram of another embodiment of a tool 100 E inserted within the bore 121 D of the driving mechanism 125 D of FIG. 3 .
- a stem 113 E may be secured to an anchor 400 E through a press fit.
- the anchor 400 E in this embodiment, is disposed farther from a bottom 150 E of the bore 121 E than a previously used anchor 401 D.
- a spacer 402 E is disposed intermediate the anchor 400 E and the bolster 101 E.
- the anchor 400 E may be secured through threads, a hydraulically activated mechanism, inserts, wedges, balls, an interlocking geometry or combinations thereof.
